This is a picture of the PCB for a Tile Bluetooth tracker.


I cant find any info on this chip, and I've looked for a while for the logo. here is a closer picture. The logo looks like three ticks, does anyone have any ideas? It should be some sort of RF front end for the Bluetooth.

Edit: I think The Photon correctly identified the logo as that of RFMD, but I'm still having trouble finding the exact part, especially since they got acquired

From what I can tell, Pin 4 is the connection to the bluetooth IC and pin 11 is the connection to the antenna. Pins 3 and 10 are connected to GND, and beyond that its not clear.

enter image description here

Finally found it! It's the RFFM6205, and the important code on the package is X8

  • \$\begingroup\$ yupp, thats definitely the one, now I just need to figure out the part number \$\endgroup\$ – BeB00 Sep 13 '18 at 23:31
  • \$\begingroup\$ Given time someone here will know that number or at least the manufacture. Then a search is easy. \$\endgroup\$ – Sparky256 Sep 14 '18 at 3:14

Reverse-engineering some of the traces to try and determine a feasible pinout could be useful.

Could be something like this, a Wi-Fi/BT integrated front-end module. Comparing the pinout of similar ICs to what you have should be a good indication of if you're on the right track or not.
